How will limited resources be protected? What budget pays for development, maintenance, platforms and bandwidth? Who brokers inter-departmental requirements and priorities? Who defines/manages schemas? DeltaPoint Solutions14 Organizational Barriers The transition to service-based reuse and integration must be bolstered by something other than enterprise altruism.
